Luke 7:10

The faith of the master is proved, and the health of the servant established, as it follows, And they that were sent returning to the house, found the servant whole that had been sick. It is possible then that the good deed of a master may advantage his servants, not only through the merit of faith, but the practice of discipline.

Matthew explains these things more fully, saying, that when our Lord said to the centurion, Go thy way, and as thou hast believed, so be it done unto thee, the servant was healed in the self-same hour. But it is the manner of the blessed Luke, to abridge or even purposely to pass by whatever he sees plainly set forth by the other Evangelists, but what he knows to be omitted by them, or briefly touched upon, to more carefully explain.

Or in another way. The centurion must be understood as one who stood foremost among many in wickedness, as long as he possesses many things in this life, i. e. is occupied with many affairs or concerns. But he has a servant, the irrational part of the soul, that is, the irascible and concupiscent part. And he speaks to Jesus, the Jews acting as mediators, that is, the thoughts and words of confession, and immediately he received his servant whole.
